Help with a regex that reads the data between two strings with irregular no. of \n

Hi,
I'm fairly new to regex and I'm struggling to get a string that can scrape data from a web page.

I need all the data between two fixed points - lets define them as "string". However the data in between could span across anything from 1 up to 6 lines. So for example it might look like this ( I've bolded string for visibility, it would not be bolded in the file ).
